An additional note, comment, or musical note that comes after the main text or melody; a supplementary remark.
From Old English 'æfter' (after) + 'note' (from Latin 'nota'). A literary and musical term combining Germanic and Latinate elements.
Musicians know 'afternote' as a technique where you play a quick note after a main note to give it texture, and it's also how footnotes work in writing—information added after the fact that actually enhances meaning.
